As many are aware, Sega Master System fans (centralized at SMS Power's forum) have long been converting Game Gear games to be compatible on the SMS using the Master Everdrive, for instance. Unrelated (you'd think), but during the 90's, Taiwanese and Korean publishers converted some MSX (originally SG-1000) games like Rally-X, Road Fighter, etc., to Master System. Why? Who knows! Well, someone discovered or obtained the software tools they used to do this. These tools have now been applied to additional MSX games with varying results. You'll have to follow the action at SMS-power, because this is all in its infancy at the moment, but cool nonetheless
